AtSim from AtLink Communications

AtLink is inspired by the evolution of advanced technologies and their application to modern traffic management systems. Taking advantage of the deep knowledge in 3D technologies and Gamification AtLink invented AtSim. AtSim is based on the belief that in the future traffic simulations will require the ability to integrate traditional static estimation approaches with dynamic historical or live traffic data with environmental data (Terrain, elevation, lighting, etc.).

AtSim integrates:

to provide highly dynamic capabilities to model and simulate time-varying traffic flows (peak & off-peak periods) combined with the influence of road geometry and environmental affects to produce a realistic traffic simulation that will identify undesired problem areas that can’t be forecasted or analyzed with static, average based systems.

3D technology

AtSim models and captures the entire network of roads, bridges, buildings, vehicles, traffic lights, road signs, lighting, pedestrians, etc. into a realistic representation.

AtSim assembles the complete network of 3D models into a realistic gaming engine. This provides the AtSim users the flexibility to navigate and travel the virtual world at ease. It gives the users the wings to fly around freely while observing the traffic flows or take a “1st person” view (as if sitting in a vehicle).

Intelligent Traffic Simulation Engine (ITSE)

AtSim’s ITSE incorporates the following features:

AtSim’s ITSE supports Macroscopic and Microscopic approaches that takes into account environmental factors such as elevation, time of day, light and weather conditions.

To provide a more realistic simulation AtSim integrates with external data sources to integrate historical or live traffic data in its ITSE engine. This enables AtSim to show realistic traffic simulations that can simulate traffic flow of a given date and a time interval to be utilized in users traffic studies.

Using the Microscopic model with ITSE AtSim can identify problem areas in the traffic network.
